Install extender bar (without washers).
1.Measure the diameter of the tube in the middle of the handlebar. If the diameter is about 31.8mm, washer is not necessary.
2.Make sure that the “extender bar” bracket is in the correct position.
3.Insert the round shaft of the small part into the semicircular hole of the big part.
4.Install a screw and tighten it.
5.Loosen the screw here and insert the round tube.

Install the double bracket extension Bar （Including the washers ）
1.Measure the diameter of the handlebar tube (Note: Please make sure that the tube at the installation location is straight)
2.Choose the matching aluminum washer according to the diameter.
3.Place the washers
4.In the same manner, install the extender bar bracket.
5.Install a screw and tighten it.
6.If the “extender bar” is loose after installation, please unscrew the screws first and remove the product.
At this time, we can use electrical tape (sorry, in order to increase the fun of DIY, we didn’t provide this electrical tape)
Wrap electrical tape around the handlebar. Put in the washer again and lock the “extender bar” bracket. In the same way, install another extender bar bracket. Insert the round tube and lock it.
